WebDec 3, 2024 · Park et al. show that medial entorhinal cortex head-direction cell discharge is internally organized but registers inconsistently and temporarily to external landmarks during navigation, indicating the navigation system operates unlike a GPS but like variably oriented etak systems without a global reference. Web7 Summary. In summary, HD cells represent a high-level spatial signal that encodes the animal's directional heading. HD cells have been identified in several brain …
WebThe head direction cells from these different brain areas exhibit the same general firing characteristics. Each head direction cell responds maximally to a single preferred direction of the head. The directional tuning curve of a single head direction cell is Gaussian or triangular in nature, and has a width in the approximate range of 500{1100 ... WebHere, head-direction cells were recorded from the post- subicular cortex (PSC) and anterodorsal nucleus (ADN) of the thalamus of freely moving rats. Cell activity was ana- lyzed in relation to both momentary head direction, and the angular velocity of head turns. Head-direction cells in PSC
